GEORGE EDMUND DONISTHORPE AND TAYLOR BURROYVS, OF LONDON, ENGLAND.

MACHINE FOR COMBING FIBROUS MATERIALS.

SPECIFICATION forming part of Letters Patent No. 482,960, dated September 20, 1892.

' Application filed January 21,1892. Serial No. 418,820. (No model.)

.To all whom, t may concern.-

Beit known that we, GEORGE EDMUND DON- ISTHORPE, merchant, residing at l2 Oat Lane, in the city of London, England, and TAYLOR BURROWS, engineer, residing at 8S Upper Kennington Lane, London, iny the county of Surrey, England, subiects of the Queen of Great Britain,have invented certain new and useful Improvements in Machines for Combing Fibrous Materials, such as Viool7 Flax, China-Grass, Silk Waste, dac., of which the following is a specification.

This invention relates 'to improvements in machines for combing fibrous materials, such as wool, iiaX, china-grass, silk waste, or the like, and we would here remark that our present machine will be found to be more advantageous for some fibers than for others. For instance, we consider our present invention more especially advantageous for fibers such as china-grass and flax.

Our present invention consists of a novel means of presenting one end of the fiber to the combing-roller or combing device, transferring such fiber to another similar part of the machine so as to present the other end of the fiber to a second combing-roller or combing device, and thereafter the ber is drawn off (after being thus combed) in one continuous sliver, or as desired.

Furthermore, our-present invention relates to a graded combing-roller or combing device having graduated comb pins or teeth thereon, and to the feeding device and other details, al1 of which willbe hereinafter fully described,

and finally pointed out in the claims.

We will now therefore proceed to describe our said invention with reference to the drawings hereunto annexed.

Figure 1 is a side elevation of the machine looking in the direction of the arrow l, Fig. 2, one part of the machine-111.6., the finishing endbeing broken off and shown in a separate View, Fig. la. Fig. 2 is a plan of the machine, the finishing end being again broken off and shown on a separate sheet at Fig. 2, Fig. 3 is a side view of a piece of the traveling endless band or carrier, shown double, which carries along the lengths or tufts of fiber and presents the same to the action of the combing-rollers, such as Figs. 9 and 10.

Fig. 4 is an elevation of the feed end of the machine-- c., looking in the direction of the arrows 2, Figs. l and 2. Fig. 5 is an elevation of the opposite end of the machine-z'. e., looking in the direction of the arrows 3, Figs. la and 2, Fig. 6 is an enlarged view, looking in the direction of the arrows 2, Figs. 1 and 2, of the feed-head and parts connected therewith, other parts of the machine being removed to illustrate more clearly the feedhead part. Fig. 7 is a cross-section, taken through the traveling bands or carriers and combing-roller on line 4: 4:, Figs. 2 and 8. Fig. 8 is a local and enlarged plan view of the combing-roller and adjacent parts, showing the relative position of said roller to the carrier-band which presents the material to be combed to the said roller. Fig. 9 is a separate enlarged plan view of the complete combing-roller, showing the graded comb teeth or pins thereon. Fig. lO is an end view of said roller.

Similar letters of reference indicate corresponding parts throughout.

ais the supporting frame or standard, of any suitable construction,carrying the fast and loose pulleys u. a', which actuate the trains of wheels and various moving parts of our machine carried in or on or supported by the said frame a.

b are two large pulleys or drums mounted in a horizontal plane and revolved by the vertical aXes b b', respectively,which are mounted in brackets, such as b2 b2, on the frame a, (see Fig. 1,) the said axes b being revolved by any suitable mechanism, such as the wormwheel a2 on the shaft a3, actuated by the pulley a', gearing with the toothed wheel b3 on the axis b', as shown in Figs. l and 2. These drums or pulleysB are slowly revolved in the direction of the arrows 5, Fig. 2, and carry around with them the endless band or bands or other equivalent device, forming the travelin g carrier A. This carrier consists, advantageously, of two endless steel or other metal bands, as shown, or one endless band only, or more than two, if desired, the upper edge of each such band A Vbeing formed with serrations or teeth A', something like comb-teeth, as illustrated in Fig. 3, into which teeth A the fiber to be combed is intermittently pressed IOO down in tufts or lengths by the feed-head or feeding device, hereinafter described and set forth, or by any equivalent or suitable means.

As the material to be combed (or tufts of ber) is pressed down across and into the teeth A of the endless band A, the latter is caused to travel along in the direction of the arrows 5, Fig. 2, as previously explained, and carries the ber along therewith toward the combing-roller B, which is mounted with its aXis parallel orthereabout to the line of travel of the carrier-band A between the pulleys b. This comb-roller B is suitably revolved by convenient mechanism (not shown) at a slow or suitable speed and the combteeth or pins B of said roller B are advantageously graded, as shown, (or in any other equivalent manner,) so as to humor the ber and not comb the same too violently at rst, but gradually and steadily comb the ber down to the degree of ueness required.

.The combing-roller Bis mounted, relatively, to the traveling band or carrier A in about the position shown in Figs. 1, 2, 4, 6, 7, and 8, and is cleaned by a brush c and doffer d, Figs. l, 2, and 6, or in any similar or convenient manner.

The ber deposited by the feed in the carrier-band A is carried along by the said traveling band A under the vertical pressingplate C, Figs. 7 and 8, the lower edge of which is slotted longitudinally, so as to overlap outside aud between the teeth on the two traveling bands A, (as shown in Fig. 7, or three separate plates to eect the same purpose may be used instead of one such plate, as 0,) so that the ber a: is passed right down and locked or very securely held in the teeth A of the carrier A. The lower edge of each band A travels in a slot or guide formed to receive the same in the bearing-plate D, Fig. 7, which is xed or mounted in the frame a. The vertical pressing-plate C may be mounted with springs, as shown in dotted lines in Fig. 1, where 2l represents a spring and 22 a block,rigidly attached to the framework above the plate C and supporting the springs, so as to give or rise a little with any extra thickness of material in the traveling carrier A. The ends w of the ber .fr-z'. e., the ends hanging outside of the band A-thus securely wedged in the said carrier A are now presented to the action of the combing-roller B, and rst to the coarse open pins or teeth, and then as the carrier A continuously travels on to the ner and ner teeth till at the end of roller B the ends as' are all thoroughly combed and nished. The ber w, with the end combed, now comes from under the end C', Fig. l, yof the wedging or pressing-plate C, and is free to be lifted out of the teeth A of the band A. The ber is removed from the band A by mechanism well known in the art-such as the plow IO-and not shown herein. The combed end w of the ber w now falls onto and into the teeth of asecond traveling band or carrier E, identical or equivalent in all respects with the rst carrier A.. Said carrier E is carried around in the direction of the arrows 6 by the two drums or pulleys e e, revolved in a similar manner to b b, and in all other respects similar lto A, this carrier E having teeth similar to the teeth A on the carrier A2, and supporting-plate similar to D, and dep ressing-plate similar to C, the object of this second carrier E being to present the now uncombed end of the ber to the action of another combing-roller F, similar in all respects to B and kept clean also in a similar manner. The ber being lifted out of the rst carrier A at the point A", Fig. 2, now falls into the teeth of the second comb E, the part already combed lying in the teeth and inside of the band E, while the now uncombed end hangs outside, and the latter is then presented to the action of the graded combingroller F in the same manner as with the roller B, the ber being so securely held in the carrier E (during the actual combing) as to withstand the pull or drag of the combingroller F as with the rst carrier A and roller B. After passing along the combing-roller F the ber is now completely combed and nished from end to end and is then drawn oif (at about the point marked H, Fig. 2a) in one continuous sliver f, by any well-known or suitable drawing-off mechanism, to which latter no claim is made, as the same is well known and well understood.

. We will now proceed to describe (more particularly with reference to Fig. 6) the feedhead or feeding device. The material g to be combed is fed in the Vdirection of the arrow 7 in beneath the plate h, and a tuft of said material g protrudes and hangs down at g', Fig. 6. The pin-plate h carries a series of pins, which pass through the ber g and e11- ter corresponding holes or apertures in a kind of grid or perforated platefibelow. The pinplate h has a vertical up-and-down motion imparted thereto by the rod j at each side thereof, so as to tightly hold the ber g and then leave the same free alternatively. This is effected by the cam 24, which is connected to the driving mechanism in any convenient way, which alternately raises and lowers the arm 25, which turns the rock-shaft 26 and the arm 27, keyed thereon, and so raises and lowers the arm j. Opposite the pin-plate h (on the inside end thereof) a nip-jaw fm works, and is operated as follows: The nip-jaw fmJ is brought close up to the pin-plate h and engages and nips hold of the tuft t', hanging out. The pin-plate is now raised (to about 125 the position shown at h) and the whole length of material g is drawn forward freely as the closed jaw m retires. As the jaw fm. retires still farther away from h, the latter is moved down and the material g is rmly held between h and vl. The closed nip-jaw m still further retires and now tears out and away from g a length of the ber leaving a tuft g of the material protruding from h i, ready for the next approach of the nip-jaw m. The

nip-jaw Ym with the .length of material asV therein now retires right back to the limit of its backward motion, whereupon the nip-jaw is mechanicallyopened and the length of ber is deposited onto the traveling band A and is pressed into the teeth of same bya dabbingbrush n, which at that moment descends, as shown in Fig. 6. The second brush o on the dabbing-brush arm p serves to brush up and prepare the protruding end g', ready for the nip-jaw m to seize on its next approach.

Having thus described and set forth our said invention, what we claim, and desire to secure by Letters Patent of `the United States,

l. In a combing-machine of the character described, the combination, with a suitable combing device, of an endless carrier for the fibrous material consisting of a plurality of bands carrying parallel rows ot' teeth on their upper edges, and a compressor plate or plates fitting betweensaid parallel rows of teeth, and adapted to hold said fibrous material between said teeth while it is being combed, substantially as and for the purposes described.
